PATENT THOMAS O. DILL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE T.C. DILL MACHINE COMPANY, OF SAME PLACE.,

APPARATUS `FOR DYEING.

SPECIFICATION forming part of Letters Patent No. 586,117, dated July 13,1897. Application filed March Z8, 1896. Serial No. 585,226. (No model.)

To all whom it may concern.:

Beit known that I, THOMAS O. DILL, a citizen of the United States,residingin Philadelphia,Pennsylvaniaiave invented certain Improvementsin Dyeing-Machines, of which the following is a specification.

The object of my invention is to construct a dyeing-machine to which canbe applied the ordinary vat now in common use and in which the vat isentirely independent of the agitating and lifting mechanism.

A further object of my invention is to so construct the mechanism thatthe yarn can be raised vertically out of the vat and then carried overto one side thereof and suspended, so that the operator may remove thedyed skeins and load the sticks with yarn to be dyed; anda still furtherobject is to so construct the mechanism that the machine will beautomaticthat is, after the sticks are loaded the machine willautomatically carry the yarn into the vat, agitate it therein for acertain length of time, then lift it out of the vat and suspend it atone side until thrown into gear again by the operatorwhereby themachines can be set by the man in charge to the length of time requiredfor a certain dye or a certain yarn, so that the mistakes due to thecarelessness and inattention of the hands in the dye-house are entirelyavoided.

In the accompanying drawings, Figure l is a side view of my improveddyeingmachine Fig. 2 is a plan view. Fig. 3 is a longitudinal sectionalview of the vat with the mechanism in elevation. Fig. 4 is a side view,partly in section, showing the dyeing-frame suspended at one side of thevat. Fig, 5 is a side view, drawn to an enlarged scale, of thepawl-and-ratchet mechanism. Fig. 6 is a View looking in the direction ofthe arrow, Fig. 5. Fig. 'F is a side view of the pawl-andratchetmechanism, showing the pawls in dif? ferent positions. Fig. 8 is asectional view of the pawl-and-ratchet mechanism. Fig. 9 is a diagramview of the pawl-and-ratchet mechanism. Fig. 10, Sheetl, is aperspective view of the ratchet-wheel- Fig. 1l ,Sheet 4, is a detailview showing the method of clamping the sticks to the yarn-frame. Figs.

l2 and 13, Sheet 5, and Fig. 14, Sheet l, are views of details of theinvention.

A is the base, made in the present instance of planks, and mounted onthis base is the vatA,cont-ainingthedyeingliquid. Secured to the base ateach side of the vat are frames A2, carrying the mechanism by which theyarn is suspended and agitated.

B is the driving-sleeve, loose on the shaft B and clutched thereto bythe clutch mechanism B2, which is operated by the lever B3. (Shownclearly in Fig. 3.) On the sleeve B is a sprocket-wheelb, around whichpasses the drive-chain. On the shaft B is a pinion b', engaging with agear-wheel h2 0n the eccentric-shaft B4. This eccentric-shaft carriestwo eccentrics c c', adapted to sockets in the eccentric-rods O and C',respectively.

The eccentric-rod O is connected to an arm d of a hell-crank lever D,while the eccentricrod C is connected to an arm d of a bell-crank leverD. Both bell-crank levers are loosely hung on the shaft E, which isadapted to bearings in the frame A2. This shaft E extends across to theframe A2 on the opposite side of the vat and is adapted to the bearingstherein.

On the shaft E at each side of the vat is an arm F. These arms are keyedto the shaft and are pivot-ed at f to arms F, which support theyarn-frame.

Pivoted to the arm F at j", some distance above the pivot f, is a barF2, which is slotted at f2 to allow for the free movement of a pin ,f2on the arm F, and on the end of the bar F2 is a pin f4, adapted to acamway a in a block a', secured to the frame A2, so that when the arm Flifts the yarn-frame it will removethe yarn-frame from the vat'in avertical line untilthe yarn is clear of the vat, andthen it will swingit over to one side, as indicated in Fig. 4.

The arms F and bar F2, as well as lthe mechanism connected therewith,are dupli cated on the opposite side of the machine, and one set 0f armsworks in unison with the other.

It will be noticed that while the arms are duplicated the mechanism foroperating the that all the intricate mechanism is at one place andwithin easy reach of the man in charge of the machine.

ln some instances the shaft E may be lengthened and a second shaft maybeplaced alongside of the vat shown, and a duplicate set of arms can bemounted on the shaft, so that two or more dye-vats and yarn-frames maybe used at the same time.

Keyed to the shaft E is a double ratchetwheel G, (shown clearly in Fig.10,) and engaging with the ratchet-teeth of this wheel are pawls carriedby the bell-crank levers D D', one set of pawls acting to agitate theyarn in the dye-vat, while the other set of pawls act in conjunctionwith the iirst set to remove the yarn-frames from the vat and to carrythem into the vat.

Referring to Fig. lO, the ratchet-wheel G has a double row of teeth onits periphery. On one row there are two sets of teeth g2 g3, beveled inopposite directions, so that the pawl that engages one set of teeth willmove the wheel in one direction and the pawl engaging the other set ofteeth will turn the wheel in the opposite direction. Between the twosets of teeth is a space g4, which allows the pawl e to simply work in agiven space without imparting motion to the wheel. The teeth on theopposite side are arranged in substantially the same manner, and at theend of one set of teeth is a stop or lug d4, beneath which the pawl d3rests, thus preventing it from lifting when the pawl d3 has reached thelimit of movement.

The pawls d2 and d3, as shown in Fig. 8, are carried by the bell-cranklever D' and engage with the ratchet-teeth g on the wheel G, Fig. l0,and when the shifting arm H is in the position shown in Fig. 8, as wellas in Fig. l, both pawls d2 and d3 engage the teeth g on the wheel G insuch a manner that the wheel will vibrate with the movement of theeccentric c', rod C', and bell-crank lever D'. This movement will beconveyed to the yarnframes in the vat through the shaft E and arms F F'and bar F2, so that the yarn-frames Will be raised and lowered during agiven number of revolutions of the main shaft, as dictated by thetime-wheel I, described in detail hereinafter.

The time-wheel is mounted on a stud t', which is screw-threaded, so thatwhen the time-wheel I turns it is moved forward on the stud, and on thetime-wheel is a lug i', which when the wheel is full out, as indicatedin Fig. 6, will rest in the path of a lug 72, on the shifting arm H.This shifting arm is pivoted at 7L' to the bell-crank lever D', asindicated in Fig. 8, and has two toes h2 h3, which project one on oneside of the arm and the other on the opposite side. The toe h2, when thearm is in the position shown in Fig. 8, rests upon one end of a weightJ, pivoted at j to the pawl cl2, while when the arm is shifted to theposition shown in Fig. 7 the toe h3 rests upon one end of the weight Jpivoted at j' to the pawl d3.

Carried by the bell-crank lever D, Fig. 5, are two pawls e e', onepivot-ed on one side of the lever and the other on the opposite side.The pawl e engages with the teeth g2 on the ratchet-wheel G, and thepawl e' engages with the teeth g3 on said wheel, and on the back of thepawl e is a pin e2, which rests in a camgroove jz in the weight J, andon the back of the pawl e' is a pin e3, resting in a camgroove js in theweight J It will be noticed on referring to the perspective view, Fig.l, that the weights J J' have cam-grooves formed by projectingportionsj2j4, so that when the pin of the pawl c enters the cam-grooveits bearing upon the surface j* will tend to hold the pawl e out of gearwith the ratchet Gwhen the shifter-arm H is in the position shown inFig. 5, so that the pawl e will simply work in the space g4 in the wheelG without imparting motion to the wheel, while the pawl e' will rideupon the cam-surfacej5 and will be lifted clear of the teeth of thewheel G, so that both pawls c e' are out of gear. The pawls are in thisposition when the yarn-frame is simply agitated in the liquid, motionbeing imparted to the wheel G and its shaft E through the pawls Z2 andd3, which are engaged with the wheel, as shown clearly in Fig. 8.

Hung to the bell-crank lever D', at 712, is a weighted pawl I', whichengages with the ratchet-teeth on the time-wheel Iland feeds thetime-wheel forward at each forward movement of the lever.

A weighted detent-pawl I2, (see Fig. 5,) pivoted to the frame of themachine at 3, prevents the return of the time-wheel, so that thetime-wheel will feed forward during a certain period until its lug i"crosses the path of the lug 71. on the shifting lever H, when the saidlug will come into contact with the lug on the time-wheel, and, as thetime-wheel is adapted to kfixed bearings, the arm H will be shifted fromthe position shown in Fig. S to the position shown in Fig. 7, releasingthe weight J and acting upon the weight J so that the pawls d3 and e'will be in engagement with their respective teeth on the wheel G andfirst one pawl will act and then the other to elevate the yarn-frame outof the liquid in a straight line x above the vat, as shown in Fig. et.At the point x the chain f5, which is attached to the shifting lever andis hooked to one of the elevating-arms, is drawn taut and the shifterwill release the clutch and stop the machine, so that the yarn can draininto the tulo, and at this point the dyer can sample the yarn, ifnecessary.

The above movement will continue if the chain is detached until thepivot of the yarnframe is at the point Fig. 4. Then the pawls c and d2,which heretofore have simply acted as followers for the pawls e' and d3,come into play and allow the yarn-frame to lower a IOO IIO

tooth at a timeuntil the lug d4, Fig. 9, locks the pawl js, which willstop this portion of the machine. j

It will be seen by the above description that two of thepawls will lockone of the bellcrank levers to the wheel G and its shaft E, so that theyarn-frame will be simply agitated in the liquid,while two cams on oneside,when the shifting arm is thrown, will raise the yarn-frame outofthe liquid andcarry it to a point directly above the mechanism, and assoon as the frame passes over the center the other pawls willfallow theframe to lower to a position at theside of the vat within easy reach ofthe operator.

The top section M of the yarncarrying frame consists of a longitudinalbar m and cross-bar fm', and on the end of the longitudinal bar are pinsm2, with which engage the arms F at each side of t-he vat. The ends ofthe arms Fare slotted, forming mouths for the reception of the pins, andeach mouth is flared, so that the pin will readily enter, and they opento one side, as indicated in Fig. l, so that when the mechanismcommences to elevate the yarn-frame the yarn is gradually turned, so asto `prevent the yarn-frame becoming disengaged. To prevent any lateraldisplacement,the ends of the pin are headed at one side, as indicated atFig. 14, andrest back of projections on the lower jaw of the mouth, Fig.l.

Suspended from the section M of the yarnframe by screw-rods p p, one setat each side of the machine, are recessed bars p', adapted to receivethe sticks s, carrying the skeins of yarn. Mounted above the bar p is aclampplate p2, which locks the stick to the bar by turning the nuts p3on a screw-rod lo, Fig. 4:. A plate p4 at each side prevents the longitudinaldisplacement of the sticks.

The bar p can be moved to and4 from the section M of the carrying-frameby means of a nut p5 on the screw-rod p, the nut p5 resting on'thecross-bar m of the section M.

Hung in the lower portion of each series of skeins is a stick s', andthese sticks are held together by the lower section M of the yarn-frame,which simply consists of two recessed bars t and t', hinged together att2, Fig. ll, and adapted to receive the ends of the sticks s. A screw s3and nut s4 lock the bars to the stick, as clearly indicated in Fig. 3.

Secured to each side of the tank, near the bottom, are brackets a2, onwhich the section M' rests during a portion of the stroke of theyarn-frame as it is agitated, so that, as indicated in Fig. 3, when theyarn-frame is lowered the upper sticks s leave the yarn, allowing thedye liquor to gain access to the space between the yarn and the stick,and the yarn will pass away from the lower stick s' when the lowerportion of the yarnframe is stopped by the brackets on the back, so thatthe liquor will gain access to the portion of yarn below the sticks.Thus the yarn is thoroughly impregnated with the dye liquor, allportions of the yarn being subjected to the liquor at each movement ofthe mechanism, and as the yarn is perfectly free during certain portionsof the time that it is in the liquor it will not kink; but when removedfrom the liquor it is completely under control, being held by the twosections of the frame.

When the yarn is raised sufficiently clear of the vat, the clamp-bars tt can be removed from the sticks s and can be supported on the vat inany suitable manner until a new batch of yarn is adjusted on the upperframe and the sticks inserted within the skeins, after which the clampscan be secured to the lower sticks. It will thus be seen that themachine is automatic to a certain extent, can be readily applied to anylength of vat, and the vat can be readily removed from the machinewithout disengaging any of the mechanism.

While I have illustrated my invention in connection with a machine fordyeing yarn, it will be understood that it may be used in connectionwith machines in which a vat is used and in which material is to besubjected to treatment of liquid in the bath and agitated undertreatment-eas, for instance, machines for washing yarn, machines forpickling metallic plates prior to plating them with tin or other metal,duc; but my invention is especially applicable for use in machines fordyeing yarn.
